1. Rubbermaid Refrigerator/ Freezer Thermometer

The Rubbermaid Refrigerator Thermometer makes reading temperature in one quick look a breeze. Each temperature marking and numbers on the meter are big, bold, and easy to spot. For even faster temperature readings, the dial is also marked with red safe zones to instantly recognize whether your refrigerator’s in the right temperature range or not.

Construction-wise, the thermometer is built from stainless steel and shatterproof glass. Its rugged construction allows it to withstand quite a bit of abuse, making it perfect for commercial kitchens. The NSF certifies it for meeting sanitary regulations and doesn’t require a battery to run.

2. SensorPush Wireless Thermometer/Hygrometer for iPhone/Android

If you want to explore the technological side of thermometers, it’s worth checking the SensorPush Wireless Thermometer. From the outside, the thermometer merely looks like a small cube. But inside, it contains both temperature and humidity sensors that consistently tests its atmosphere.

The best part is that you can receive all of this data straight on your phone in structured graphs. All of the information is transmitted through Bluetooth, and the sensors can send data as far as 352 feet without any significant obstructions in the way. You can also receive alerts when a figure drops or rises too sharply. The app is also relatively straightforward and available on both iOS and Android.

Despite its simple design, the thermometer can read temperatures between -20°C to -60°C. You can also stick it inside your door with the magnets on its back, stand it on a surface, or use the hook to hang it on the refrigerator shelves. 

At the back, you just have two buttons; one that powers on/off the thermometer and the other, which selects Celsius or Fahrenheit.

4. CDN TA20 Audio Visual Refrigerator Freezer Alarm

The CDN TA20 Refrigerator Thermometer’s smart wired-sensor design allows you to view temperature readings without opening your fridge repeatedly. Its main unit attaches to your fridge’s door with the help of velcro tabs, while the sensor attaches to the inside through a suction cup.

Because of the unique wired design, you don’t have to repeatedly open your refrigerator to ensure it’s maintaining optimal temperature. And the bold fonts make it easier to catch the temperature readings in a glance.

If the temperature falls below 15°F or 45°F, the thermometer automatically alerts you by flashing LED lights or an audio signal. Both of these can be turned on and off through the alert switch. 

5. JSDOIN Freezer Refrigerator Refrigerator Thermometers

Another classic analog thermometer on our list is the JSDOIN Thermometer. From the outside, its constructed like any other durable refrigerator thermometer. It’s built from stainless steel for protection against corrosion, and you can either stand it up or hang it as per your preference.

But the dial is the most prominent feature of this thermometer. Apart from the temperature readings, the entire dial is also marked with different colors for each type of environment. So instead of squinting closely to read the dial, you could simply check if the needle is on the right color range to ensure that your refrigerator’s working correctly.

This particular offer includes two thermometers to place one in your fridge and the other in your freezer.

On the front, you’ll find three simple buttons; one switches between room and fridge temperature, one sets the alert, and one switches between Celsius and Fahrenheit. The monitor can be attached to the refrigerator with a magnet, hung through a keyhole, or set on a flat surface.

Feature-wise, the thermometer can measure temperatures between -58°F to 158°F accurately. The sensor wire is water-resistant, and the thermometer can be set for a high or low-temperature alarm. 

Buyer’s Guide

Whenever you’re purchasing a thermometer for your refrigerator, you’re fully trusting it to register accurate temperatures. Since the freshness of your produce depends entirely on this tool, it’s crucial to make the right buying decision to avoid any major incidents.

So if you’re looking to purchase a reliable and long-lasting thermometer, here are some features and factors you should consider:


Probably the most critical aspect for a thermometer is accuracy. Because you’re putting all your trust in this little tool, it should never occur that the temperature it’s displaying is -5°C, when in reality, it’s 2°C. In such cases, by the time you realize that the cooling seems a bit off, most of your produce would have already spoiled. 

An accurate and reliable thermometer will precisely measure temperature without needing frequent calibrations. It will also mention the margin of error, which is usually +/- 2°F for most good quality thermometers and is suitable.

Temperature Range

Would you take a car that doesn’t go above 40mph to a NASCAR race? Probably not. Same is with thermometers. When you’re buying a thermometer for your fridge, you have to make sure that it can measure the temperatures that your refrigerator runs at typically. 

Usually, a good refrigerator thermometer has a range between -20 to 80°F or -30 to 30°C. This range is good enough for most home refrigerators as well as freezers. However, it never hurts to have a thermometer that has an even broader range.

Multiple Placement Options

A good thermometer will always have more than one placement option. Most basic thermometers have a wide stand, which allows you to set them on a flat surface in the refrigerator. A hook will enable you to hang it on a wired shelf so that it doesn’t gets in the way of stuff.

Most external thermometers can be attached through magnets or tapes, but sometimes they also have stands if you want to place them on any flat surface. 

Easy to Read

Using a thermometer that’s easy to read not only saves time but is also much more efficient. This is especially important if you work in a commercial kitchen where staring at a thermometer for several minutes isn’t practical.

Reading the temperature on a digital thermometer is a breeze. Because the numbers are displayed in big and bold fonts, a quick glance can let you know what temperature your refrigerator’s at. 

But with analog thermometers, things can become a bit difficult. However, most analog thermometers also have colored markings alongside the dial. So if you’re in a hurry, you can just take a quick peek at those markings to see if the needle’s in the safe zone.

What's The Ideal Temperature For Your Refrigerator?


Since you’re keeping these thermometers along with your precious produce, it’s essential that it does not build any germs or contaminate your food. Most analog thermometers are constructed from stainless steel, which is both corrosion and rust-resistant and so lessens the chances of contamination. 

Plastic is also resistant to the buildup of bacteria but should be wiped down with a tissue paper or clean cloth from time to time. This helps ensure that no bacteria ever reach or contaminate your food.


What is the correct temperature for a fridge?

A fridge should always be below 40°F or 4°C to prevent food from spoiling. On the other hand, a freezer should be below 0°F or 18°C to maintain the quality of the food.

What does the number on the temperature controller indicate?

The numbers on the temperature controller in a fridge usually indicate the refrigerator’s freezing power, not the temperature. So if you set it at 1, cooling will be at its lowest and increase as you adjust it to a higher number.

What is the best spot to place a refrigerator thermometer?

The warmest place in the refrigerator is the best spot to place the thermometer. This is usually a spot that’s furthest from the back i.e., the door or right at the front.

Why is my fridge not getting cold?

Usually, cooling problems occur when the coils at the back are blocked. To clean them, turn the fridge off and vacuum it to remove any debris or dust impacting the cooling.

How does a Refrigerator work ?

What is the coldest part of a refrigerator?

In freezers, the coldest part is usually the bottom as cold air sinks. But in a single-door refrigerator, the coldest part is generally at the top near the ice cube box.
